FRANK R. STEELY, F HAMBURG-,PENNSYLVANIA.

ELEVATOR.

Application filed May 6, 1915.

T 0 all whom it may concern Be it known that I, FRANK R. STEELY, acitizen of the United States, residing at Hamburg, in the county ofBerks and State of Pennsylvania, have invented certain new and usefulImprovements in Elevators, of which the following is a specification.

My invention relates particularly to refrigerators of the class whichresemble a dumb waiter and which are commonly known as disappearingrefrigerators, and is especially directed to the mechanism whereby therefrigerator body is raised and lowered and maintained inits respectivepositions.

The principal objects of my invention are to provide a refrigerator ofthe class described, with means tending to thrust the cage or bodyupwardly through the floor, to provide means for retaining said cage orbody in its position beneath the floor, and to provide means to releasesaid retaining means.

Other objects of my invention are to provide a refrigerator of the classdescribed with shock absorbing mechanism which is effective at thetermination of either the upward or downward movement of the cage orbody, and to provide guiding mechanism wholly disposed beneath the floorfor directing said cage or body vertically.

My invention comprehends a stationary guiding frame, for movablysupporting the cage or body, having adjustable legs movablelongitudinally to vary the length of said frame.

My invention also includes all of the various novel features ofconstruction and arrangement hereinafter more definitely specified.

In the accompanying drawings Figure 1 is a side elevational view of arefrigerator conveniently embodying my invention; Fig. 2 is a frontelevational view of the refrigerator shown in Fig. 1; and Fig. 3 is aplan view of the structure shown in Figs. 1 and 2, with the floorremoved.

In said figures the cage or body '5 is mounted for vertical movement inthe stationary frame comprising the standards 6, 7 and 8 disposed uponopposite sides thereof, the standards 6 and 7 being connected. by thetransverse tie 9 and the standards 7 and 8 being connected by thetransverse tie 10 at their lower ends.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Serial No. 26,208. i

The upper ends of the standards 6, 7 and 8 at the respectively oppositesides of the cage or body 5 are connected at their upper ends by therectangular housing adjacent to the under surface of the'floor 12, and"com prising the front and rear walls 13 and'14; and side walls 15, andposed between joists 16.

The cage or body 5 is supported upon the cross-bar 17 which carried bythe cords or chains 18 which are respectively attached to its oppositeends and which pass over sheaves 19, mounted insuitable bearings 20 onthe side walls 15, and have their'ends connected with suitable weights21 which are mounted to slide up and down between the standards 7 and 8.

The standards 7 and 8 are provided in thelr opposed faces with grooves22 and 23 respectively which serve as guides for the lugs 25 on theweights 21. r

The cage or body 5 is provided upon its opposite sides, near the front,with vertically extending rails or ribs 26 which pass through the guides27 on the respective standards 6 and cooperate therewith to maintain thevertical position of said cage or body 5 as it moves up or down, and isalso provided with rollers 28 arranged to traverse the opposed faces ofthe standards 6. I I

The cage or'body 5 carries the transverse bar 29 having the verticallydisposed rods 30 which loosely extend through the transversely disposedbars 31 and 32 and have heads 33 for retaining the bar 32 thereon. Thebars 31 and 32 are normally separated by spiral springs 35 whichencircle the respective rods 30, and extend somewhat beyond the ends ofthe bar 29 so that the bar 31 may engage the lower edge of the side wall15 in the upward movement of said cage, and the bar 32 may engage theupper edge of the stops 36, projecting inwardly from the standards 6 asbest shown in Fig.

arranged to be disl, in the downward movement of said cage. 7

are pivotally supported in suitable bearing frames 42 respectivelysecured to the inner faces of the side walls 15 of the housing.

The detent hooks &O are normally forced into engagement with the cleats41 by the springs 43, best shown in Fig. 3, and are arranged to bewithdrawn therefrom by the bell-crank-levers d5 which are pivoted on thebearing frames -12 and which have one arm engaged in a suitably providedaperture insaid detent hooks, and the other arm connected by the link &6with the rocker arm 47 of the rock shaft L9.

The rock shaft i9 is mounted to rock in the bearings 50 on the rear wall1% of the housing and is provided with rocker arms 51, either of whichmay be connected by the cord or chain 52 with the foot treadle 53, bypassing through said wall H and around the sheave 55' which is mountedin the bearing frame 56 on the joist or other suitable support 57.

It will be observed that the treadle 53 is centrally pivoted in thebearing 58 within the shield 59 and has the foot piece 69 so that whenthe operator presses upon said foot piece the tail 61 of the treadlewill be raised and the rock shaft i9 rocked in its bearings whereby thebell-crank levers through their connection with the rocker arms 47 arerocked to effect the movement of the detent hooks %O in opposition totheir respective springs and ther by release them from the cleats d1.lVhen thus released the cage or body 5 is shot upwardly through theopening in the floor 12 by the weights 21 which descend between theirrespective guides comprising the standards 7 and. 8, until the bar 31engages the under edge of the walls 15 of the housing which tends tocompress the shock absorbing springs 35 and arrest the further movementof said cage.

In order that the stationary frame may be readily adaptable to varyingdistances between the floors, the standards (3 and 8 may be providedwith adjustable extension legs 63 and 65 each having a slot 66 throughwhich the stud bolts 67 having the nuts (38 and washers 69 extend, thusit will be seen that by loosening the nuts 68 said legs may belongitudinally shifted into any vertical position as shown for instancein dot and dash lines in Figs. 1 and 2.

The cage or body 5 may be conveniently provided with a plurality ofdoors 70 and 71 in the front, while the sides and back may be providedwith. openings 72 provided with reticulated fabric 73 as shown in Fig.l.

i do not desire to limit my invention to the precise details ofconstruction and arrangement herein set forth, as it is obvious thatvarious modifications may be made therein without departing from theessential features of my invention as defined in the appended claim.

v aving thus described my invention, 1 clann:

In a lift comprising a reciprocat ry cage arranged to rise and fallthrough the floor, the combination with a stationary frame, of a cagemovable in said frame and having depending rods provided with heads attheir free ends, cross-bars loosely carried by said rods, and springsbetweensaid crossbars tending to force one upwardly and the otherdownwardly.

In testimony whereof I allix my signature.
